VAPOR-BURNER.

SPECIFICATION forming par: of Letters Patent No. 363,863, aatea May s1, 1887.

Application filed September 2, 1886. Serial No. 212,511. (No model.)

To (LZZ whom it may concern:

Beit known that I, GEORGE M. VOLTZ, a citizen of the United States, residing at St.

\ Joseph, in the county of Buchanan and State of Missouri, have invented a new and useful Improvementin Vapor-Burners, of which the following is a specification.

My invention relates to vapor-burners; and

it consists in the peculiar construction and 1o combination of devices, that will be more fully hereinafter set forth, and particularly pointed out in the claims.

In the drawings, Figure 1 is a Side elevation of a vapor-burner embodying my improvement. Fig. 2 is a vertical sectional view of the same.

A represents a vapor-burner which may be either of the construction herein shown or of any other suitable form, and is provided with 2o adepending arm, B, having' near its upper end a horizontal hollow arm, C, the boreof which communicates with the inlet-pipe D. In the upper part of the arm C is formed a jet-orifice having a seat, E, for the reduced upperend of the vertically-movable needle-valve F. A

sleeve, G, depends from the lower side of the arm C, and to the said sleeve is clamped the usual drip-cup, H.

I represents' a horizontalbracket-arm,which 3o is secured to the lower end of the depending arnI B by means of a screw, K. A vertical opening is made in the outer end of the said bracketarm, and the said opening is directly f in line with the bore ofthe sleeve G.

The needle-valve is formed of two sections, ff?, which are connected by a screw-coupling, fi, which is interiorly screw-threaded, and is provided with a seat, f3, at the upper end for the lower end ofthe upper valve section. They lower section of the valve is rigidlyseeured in the vertical opening of the bracket-arm I by means of a set-screw, Il, and the upper section of the needlevalve extends up through the hollow sleeve, as Shown.

From the foregoing description it will be readily understood that by partly turning the coupling of the needle-valve in one direction the Said needle-valve will be lengthened, soas to cause the needle-point to rise in the minute opening in the valveAseat, and thus close the same and cut off the supply of fluid from the burner. By vturning the coupling in the conthe needle-point, thus causing thelatter to be 5 5 Withdrawn from the openingin the valve seat. In order to turn the said coupling, I provide it with a handle, M, which is clamped firmly thereto by a set-screw, N.

The lower end of the sleeve G, through 6o which the upper section of the needlevalve extends, is screw-threaded, and is provided with a packing-box, O, whereby leakage of the fluid or Oil is prevented. Y

It will be noted that that portion of the needle-valve which extends through the sleeve is plain, and is not provided with screwf threads. This permits an exceedingly tight joint to be formed between the upper section of the needle-valve and the sleeve through 7o whichit passes, which'is not subject to wear, and thus the danger of the burner leaking is obviated.

Heretofore, so far as I am aware, the needlevalves of vapor-burners have been provided with screw-threads and work in interiorlythreaded sleeves. This construction is objectionable, for the reason that the said valves frequently become clogged by the condensation of the fluid, thus rendering it extremely dif- 8o `cult ,to turn the valve, and is also objectionable for the reason. that the screw-joint thus formed is very likely to leak, thus frequently causing disastrous consequences. These objections are overcome by the construction hereinbefore shown and described.

If it be desired to remove the needle-valve for any purpose, the screws K and L are loosened, thereby permitting the lower section of the'needle-valve lo be withdrawn from the 9o bracket-arm, and the latter is then swung to one side, out of the way, and the upper section of the needle-valve may thon be easily withdrawn from the sleeve.

I do not desire to limit myself to the precise construction hereinbefore described, as it is evident that modifications may be made therein without departing from the Spirit of my invention.

Having thus described my invention, I roo claim 1. In a vapor-burner, the combination of the sleeve G, having the orifice E, the needlevalve section F, fitting in the sleeve and movable longitudinally therein, the rigid screwthreaded section f', below the section F, and the turning coupling-sleeve f2, interiorly threaded and screwed to the section f', and having the seat for the lower end of the section F, substantially as described.

2. The combination, with a vapor-burner, of the rigid needle-valve section f', provided with screw-threads, the va1ve-section f, having the point, and the couplingf2, having the interior threads engaging the threaded section f and provided with the seat for the lower end of valve-section f, substantially as described.

3. In a Yvapor-burner, the eombination'of the sleeve G, having the'orice E, the needle valve section F, movable longitudinallyin the sleeve and having the point, therigid screwthreaded section f', arranged in line with and below the section F, the screw-coupling sleeve interior] y threaded and connecting the opposing ends of the valve sections, and the lever or handle M, attached to the coupling-sleeve. to turn the latter, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
